ADJUSTAB E surronrme DEVICE.

Application filed July 18,

This invention relates to an adjustable support and it appertains more especially to such a device which is attachable to a bedstead or the'like.

The main object of the invention is to provide a device of the character described capable of being adjusted so that a person taking any posture relatively thereto may conveniently view and reach such articles as are placed on the device.

Another object is to produce a device of the nature set forth adapted for adjustable attachment to a primary support which may be either a bed-stead, or a floorstand, or the wall of a building.

A further object is the production of a device of the type specified embodying adjusting means whereby an article-supporting member may be pivoted in either a vertical, horizontal or any intermediate plane, besides raised or lowered and translated, as well as moved in arcuate paths at substantially right angles to each other.

Still another object is the provision in a device of the class mentioned of detent mechanisms resiliently held in engagement while permitting interrelative adjustment therebetween. I

A still further object is to furnish a device of the kind referred to with instrumentalities serving to retain a book placed on the before named supporting member irrespective ofthe position the latter is made to occupy, but at the same time admitting of the books leaves being turned over.

An additional object is to supply a device of the genus alluded to composed of few, simple and durable parts of light but strong construction, readily applied or removed, conveniently adjusted as well as easily maintained in position and operated, besides being amenable to low cost of manufacture.

Other objects and advantages of the invention will become apparent as the specification proceeds.

lVith the aforesaid objects in view, the invention consists of the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated on the annexed drawings, wherein like parts are designated by the same reference characters throughout the several views.

Briefly described, the invention under consideration includes in its organization a 1921. Serial No. 485,695.

upon any convenient primary support suchv as a bedstead, stand, or wall. I

The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined in the one and same structure, but, useful devices may be produced embodying less than the whole.

It will be obvious to those skilled in the art to which the invention appertains, upon becoming conversant with the details thereof, that the same may be incorporated in several different constructions. The accom panying drawings, therefore, are submitted merely as showing the preferred exemplifiestion of the invention.

In the said drawings Figure I is a front view of this improved.

device, showing it attached to the bed end of a bedstead;

Fig. II is a side view of the construction shown in the preceding figure;

Fig. III is a top plan view of the same construction Fig. IV is a rear view of a detail appearing in Fig. I;

Fig. V is a side view of a modification embodying the same invention;

Fig. VI is a plan view of a detail shown in Fig. V; and

Fig. VII is a fragmentary rear elevation of another detail involving a further modification;

Referring now to the said views for-a detailed description of the invention the reference letter A designates a primary support which may be the head end of a metallic bedstead of a common type. At a convenient distance from the toprail or edge of the latter is located a horizontally disposed support 11 which may be in the nature of a as sheet inost eieny is Fig. I.

pair of tubular members or guides suitably spaced one from the other. As shown, the extremities of these guide members are provided with right angularly ofiset portions or V claws 12 adapted to engage the posts of the bedstead from the inner sides thereof. Coacting with the outer sides of the said bed posts are clamps 13 having inwardly directed toeportlons 1% arranged to rest in notches 15 formed enclwise in the gmdes 11.

Screw-bolts 16 passed thru the intermediate,

Theserollers have their faces grooved, and are revolvable on spindles 21 beiiig located "so as to take oi ei and iinderthe top and bottom edges: resp'ect'i ielj of the said guides 11 at given distaiiees apart thereon. As seen to best advantage in Figs. I to III the opposite longitudinal edges of the Carriage 19 are extended outward and thence downwaiedly, or upward, forming curtain walls 22 in which the ends of the said spindles 21 are supported. Meaiis are proiiided for locking the carriage 19 in a jaredeterinined position on theg'uides 11. The said locking means may consist oii a thumb screw 23 threaded into the bottom ijortioii of the said carriage and bearing with its against the underside of the adjaoent lower guide From "he rear face of th carriage ex tends out a socket 24: thru wlnch is passed aisleeve 25 having fixed thereon a r170 26.

This rib is reoeived withiii a channel 27' formed oinjble iheiitarj to the said asket, and a thumb screw 28 bearingiifjoii the rib fiom the channel holdfscth said sleeve at the desired elevation. The latter carries at its upper eiitreniity head 29, the surfaee whereof is dentated. Steiner) hav mg a heiizontauy disposed am 31 is] ranged tohave its vertical leg which is adjacent to the primary siijip'ort, passceiir trally thru the sleeve as wellas the head thereof. A detent 32 aiiixd to the said stein coa cts with the dentations the head 29 ceretain the stem in de'slred angular relation to the carriage l9 and the thereby supported socket 24 and sleeve 25. Intermediately of a stop 33, suchas a ,nutior the like, on the stems lpwe extiennty and of therbottoin e'nd of the sleeve 25, is interposed a coilspring 34 whi'h' acts to draw the detent 32 intoirltiinat'eoontact with the dentations in the head 29,1 while peri'nitjting interrel'ative movement tlieiehe'tween, if siu'h'cient strain is ap'jjlie'd to the arm 31.

Upon the latter is slidahly as well as osi11 tab1y mounted a hollow hub 36 provided at oiie side with serrations 37 and adjustably held to the arm 31 as by a thumb screw 38. A c'lisc-sh'aped head 40 at the upper end of a rod 4-1 is formed with similar serrations to those first named and adapted to coact therewith. Interposed between the said head 40 and the head of a belt or screw 42' passing thru the former and secured in the hub 36 is a compression spring; 4.3 which urges" the companion serrations into engage ment, but is capable if strained beyond a certain degree, of allowing the serrations to slip past one another. I

Ali eXtens'ioii 45 of tubular nature is tele seopic ny as well rotatahljr connected with the sai'd'rod L1. The afemme'ntiened parts, 41, 4:5, form outeror free 1eg'w1ii'ch together with the arin 31; and adjacent leg 30' constitute an inverted substantially U- shaped structure that 1 is carried by the primary suppers I Disass'oci'ation of the former from the latter is prevented thrii the instrumentality of an enlargement 46 at the lower or free terminal of ther'od finch ingan abutment against theinner contracted 'edg'e ofthe upper endfi'? of the tubular or tain the said extension at any desired point 1 ations,,.thos on the first mentioned head 510i the pm, being in coasting release with the serrations 50. A other disc shaped head 53, has serrations- 54 incorp rated in its has designed to engage bon-espondi g ones an the sane-head of t e pair 51', 52. Forth purpose-bf adjhfstahly holding gethr the said heads 49, 51 and 52, 53, screw sons 55, 56threa'ded into the heads '51 53 hate ii orltiii' lit in the disc or- 7 1 C) r v tionsof the stepwise heads 49, 52.

ream. the disc-h'ead 53 projects out in an axial directioii boss 60 to which is secured by one edge article carrier or supporting member 61 having at the opp osite'edge thereof an upstanding lip 62. Associated with the said member is a retainer 63 reaching longitudinally across the same as well as yieldably connected thereto. The means of connection may consist as shown of screw bolts ca aflixed to the ends of said retainer and movable in slots 65 formed in proximity to the transverse side edges of the member. Between the underside of the latter and the heads of the said screws 64 are interposed springs 66 tending to keep the retainer against the said member. By virtue of this construction a book or newspaper placed upon the carrier member 61 will be held fiatwise thereon. It will be noted that the retainer 63 has its middle portion 67 reduced in order to clear the backing of a book l3 laid on the member. It is only necessary that a. small portion of the retainers inwardly bowed or tapering edges should bear upon the upper outer corners of the boolrs leaves to hold the latter from turning'over. Besides, this makes it convenient to withdraw one leaf at a time'from either of the retainers edges, turn it over, and then tuck the same under the reversed inclined side edge of the retainer. Approximately opposite to the lip 62 of the member extends out frontwise beyond the latter an arm 69 in which is held as by means of a thumb-screw 70 a finger 71, capable of reaching partially over the lower portion of the book B, keeping the same from falling oil no matter at what inclination the said member is placed.

From the foregoing it will be obvious that the supporting member 61 can be swung on the screw bolt 55 as a fulcrum to any location between inverted or converted horizontal positions. At the same time, but independently of the former movement, the member may be turned on the belt 56 in a plane at right angles to the one first named. Furthermore, rotation of the extension barrel 4-5 around the rod ll affords the member a secondary pivotal motion. Besides, it may be raised or lowered due to the telescopic conuection between this rod and its extension. Other changes in the elevation of the parts last named can be effected thru the sliding adjustment of the sleeve 25 in the socket 24, the former being so arranged that the stem 30 may be moved arcuately therein relatively to the said socket. In addition to these adjustable features, the hub 36 can he slid in or out on the arm 31, while contemporaneously it may be oscillated from one side to the other upon the latter.

Thus it will be seen that a person sitting or reclining face up or on the side in the bed may have the member so adjusted that any reading matter placed thereon, can be conveniently viewed without imposing an undue strain on that persons eyesight. Further it will be understood, that instead of supporting papers and the like on the member, a

tray or dishes with food may be put on it, so that an invalid lying in the bed will be afforded greater convenience in reaching the same than if these articles were placed on a table or chair beside the bed.

In case, it is found unsuitable to fit the guides with the carriage 19 to the bed as a primary support, an upright C having a foot D such as is illustrated by Fig. V can be made to stand on the floor directly. in rear of the head of the bed. In thismodilied construction the sleeve 25 embodying the socket 2st, is vertically adjustable on the upright C. The latter if desired may be of square cross section so as to hold the said socket against rotation thereon. A thumb screw '28 bearing upona leaf spring 26 forces the same sulliciently hard against the adjacent side of the said upright to maintain the sleeve, the stem and the therewithcoacting elements, at the desired height.

Fig. VII represents another modification,

wherein the guides 11 which translatably sustain the carriage 19 are secured to cleats E one of which only 1s shown. The cleats are adapted for bolting to a primary support. It will thus be possible to mount the device on wall over a couch or like piece of furniture possessing no means to which the guides can be attached, with the further advantage that neither foot nor stand is re quired, while at the same time all operating parts are inconspicuously disposed outof the way.

While certain preferred embodiments of this devic have been shown and described, it will be understood that changes in the form, arrangements, proportions, sizes and details thereof may be made, without departing from the scope of the invention as defined by the appended claims.
